IMPROVEMENT IN FELT-GUIDES FOR PAPER-MAKING MACHINES.

Specification forming part of Letters Patent N0. 216,696, dated June 17,1879 application filed January 16, 1879.

To all whom it may concern:

Be it known that I, JACOB PEASLEE, of

Ashland, in the county of Grafton and State of New Hampshire, haveinvented a new and Improved Felt-Guide for Paper-Making Machines, ofwhich the following is a specification.

My invention relates to guides for the felts of paper making, leather,and straw-board machines, whether wet or dry felts, and also for thewires of the Fourdrinier machine; and the invention consists in an upperand lower roller mounted upon a pivoted frame, the up per roller havingconical pressure-surfaces, that act in connection with the movement ofthe pivoied frame, to retain the felt in a central position. The guideis adjustable for felts of different widths.

In the accompanying drawings, Figure 1 is a vertical longitudinalsection of a felt-bed having my guide applied thereto. Fig. 2 is across-section on line a w;

Similar letters of reference indicate corresponding parts.

A is the bed; a a, the end rollers, over which the felt b runs. Thecenter roll, 0, for the felt is journaled in a frame, at, that ispivoted on a pin, 0, that passes through the center crossbar, f. Thisconstruction permits horizontal swinging motion of frame d,- and toreduce friction, the bar f is beveled. at each side of pin 0, as shown.

Above roll 0 is the guide-roll g, journaled on frame 0 in sliding boxesh, which are fitted with spiral springs l, for retaining the roll 9 uponthe felt with spring pressure, which should be rendered adjustable.

The roll 1 consists of a shaft carrying conical bosses i, that aresecured adjustably at opposite ends of the shaft, and with their largerends outward, so that their inclined surface will bear upon the edges offelt I) and the pulp will have room to pass beneath.

The standards of frame e are connected to the horizontal bar bymortise-andtenon joints, secured by screws 70 passing through slots,which permit frame 6 to be lengthened or shortened for adaptation tomachines of different widths.

The described construction permits the adjustment of the guide for feltsof various widths, and in case of shrinking in anew felt the conicalbosses t can be set up accordingly.

In operatiomthe guide will be self-actin g to retain the felt in thecenter of the rolls, and prevent its becoming injured by running off theside.

The action of the conical pressure-surfaces will be to swing frame 0 toan inclined position when the felt has any tendency to either side, andprevent the felt from running 011'.

This invention will save the labor of an attendant heretofore requiredto watch the felts and adjust the guide by hand, and also permits theuse of a much narrower felt than heretofore used.

The rolls may be made of wood, iron, or other suitable material. I donot limit myself in that particular, nor to the application of myinvention to any special machine. It may be applied to guide the wire ofa Fourdrinier paper-machine and for wet or dry felts.

Having thus described my invention, I claim as new and desire to secureby Letters Patcut- 1. In a paper or straw-board machine, thecombination, with the wire or felt, of the rolls 0 and g and pivotedframe 6, the roll 9 being provided with conical bosses 2 substantiallyas described and shown, and for the purpose set forth.

2. In a paper-making machine, the combination, with the guide-rolls oandg, of the swinging frame 0, that is adjustable in length, substantiallyas and for the purposes specified.

JACOB PEASLEE.
